The document discusses CEREC, a dental system that allows for ceramic fillings, crowns, veneers, and other restorations to be made and placed in a single dental appointment. CEREC restorations offer benefits like a natural appearance, lack of metal components, and conservation of healthy tooth structure. The CEREC system creates restorations from 3D scans of the teeth and mills them from ceramic blocks, eliminating the need for impressions, temporary fillings, or multiple appointments. Clinical studies show CEREC restorations have durability equivalent to gold restorations.
